An attempt to serialize the attribute information failed. (J2EE application = aa....aa, context root = bb....bb, HTTP session ID = cc....cc, attribute name = dd....dd, invalid class = ee....ee)

aa....aa: J2EE application name
bb....bb: Context root name
cc....cc: Session ID of the HTTP session
dd....dd: Name of the attribute that failed to be serialized
ee....ee: Class name of the object that failed to be serialized

Description

An attempt to serialize the attribute information of the HTTP session is failed. The information of this HTTP session is not duplicated on the EADs server.

The cause of failure in serialization might be as follows:

• The object, referenced from the object of the attribute that failed to be serialized, was not a class that can be serialized
• The writeObject(java.io.ObjectOutputStream out) method was implemented, and an exception occurred during serialization.

Action

Identify the cause of the failed attempt to serialized the attribute information based on the contents of the stack trace that is output with the message ID KDJE34412-E to the Web servlet log, and then take any of the following actions:

• Exclude the object in which the error occurred from the attribute of the HTTP session.
• Change the Web application and remove the cause of the error, from the object that failed to be serialized.
